Table 1. Ranking of transmission routes. Ranking of transmission routes by the proportion of inferred ancestries based on social network patterns. Column percentages add up to 100%. The overall rank was inferred from the sum of ranks of all scenarios.

Weight Description Scenarios Rank
[birth_Basic] [birth_E] [birth_S] [shed_Basic] [shed_E] [shed_S]
6 Cow-to-calf 0.0% 0.0% 4.0% 1.0% 0.0% 3.0% 7
5 Calf-to-calf 5.9% 6.9% 11.9% 3.0% 4.0% 11.1% 5
4 Adult-to-adult contact during the infectious period 24.8% 49.5% 42.6% 33.3% 69.7% 59.6% 1

a For 128–101 = 27 isolates (in [birth] scenarios) and for 128–99 = 31 isolates (in [shed] scenarios), no ancestor could be found within the genomic distance threshold of 6 SNPs and, thus, no transmission route could be inferred. Each of these 27 and 31 isolates was the root of a separate transmission tree.
